Southern California -- this just in

Giants fan Bryan Stow, who was severely beaten after the Dodgers' home opener in March, was upgraded from critical to serious condition, doctors in San Francisco announced Wednesday.

At a news conference, doctors at San Francisco General Hospital said Stow was opening his eyes and showed some movement in one arm.

Stow was in a coma for weeks after the attack and suffered brain damage.

Two men attacked Stow, a 42-year-old paramedic, in the parking lot of Dodger Stadium on March 31 after the rival teams played their season-opening game.

Though Giovanni Ramirez, 31, was arrested three weeks ago in connection with the beating, Los Angeles County prosecutors have yet to charge him in connection with the attack. Prosecutors asked police to gather more evidence in the case, and LAPD officials said they hoped to present the case again soon.

Police Chief Charlie Beck has said detectives strongly believe Ramirez beat Stow and have enough evidence to prove it. Ramirez's family insists he was at home at the time.
